Use 1-2 300cc oxygen absorbers in 1-gallon containers. Use 5-7 300cc oxygen absorbers or one 2000-cc oxygen absorber for 5-gallon buckets.


How Do You Know What CC Oxygen Absorbers to use?

In order to choose the appropriate oxygen absorber size, you’ll need to know how much oxygen is currently contained in the container. 

The unit of volume for oxygen is the cubic centimeter (cc). Our oxygen absorbers are scaled in size to the quantities of oxygen they are designed to absorb. For instance, a 300 cc oxygen absorber can take up that much oxygen.

What is the Difference Between 100cc and 300cc Oxygen Absorbers?

A single 100 cc oxygen absorber will suck up 100 ccs of oxygen. Remember that oxygen makes up around 20% of the air we breathe, and nitrogen makes up the other 80%. 

So only oxygen is removed by the oxygen absorbers. These larger and more powerful oxygen packets come in 300cc and 500cc capacities.


Can you use Too Many Oxygen Absorbers?

A greater quantity added will have no negative effect on the meal. This is because the amount of oxygen inhaled is equal to 20% of the entire volume of air, or the number of cc’s above.


When Should You Not Use Oxygen Absorbers?

When preserving foods that have more than 10% moisture, O2 absorbers should never be used because they can lead to botulism sickness. In addition, nuts, seeds, and whole grains (and other foods) that are high in oil content tend to spoil more quickly.


How Long Do Oxygen Absorbers Last Once Opened?

Absorbers have a very short shelf life once the package has been opened. Therefore, once you remove them from the packaging, you should use them within 15 minutes. You can keep the unused packets for up to six months in an airtight PETE container or glass jar.


Final Thoughts on How Many CC of Oxygen Absorbers Per 5 Gallon Buckets?

Since 1-2 300cc oxygen absorbers are used for 1-gallon containers, then 5-7 300cc oxygen absorbers are required for 5-gallon containers. You’ll need to know the amount of oxygen in the container to determine what absorber size you need. 

However, using greater quantities of oxygen absorbers will have no negative effects. But once you open one, you have 15 minutes to use them.
